It’s Not Just About Estrogen

If you’ve landed here I’m guessing you’re older than 40 and I’ll wager that it’s not you but your hormones causing you to feel like this.

What exactly are hormones anyway?

This is such a good question particularly in view of all the hormone talk around the world at the moment. Many of us nod our heads sagely but do we really understand? Possibly not, so here’s a quick rundown.

We have about 50 different hormones in our bodies related to such things as reproduction, growth, metabolism and stress.

Hormones are chemical messengers secreted by the tissues into bodily fluids, which transport them to different cells and organs in the body. Once they reach their destination they act like an instructor influencing growth and behaviour.

For example adrenaline/cortisol sends a message to the brain to tell the heart to beat faster when it thinks we’re in danger.

The sex hormones

When it comes to our reproductive system and peri and post-menopause most of us immediately think of estrogen. It’s our most well known sex hormone and it’s often associated with the overall subject of menopause.

But if we know a little bit more about our sex/reproductive hormones then we might add progesterone to the mix because estrogen and progesterone work hand in hand when it comes to our reproductive cycle.

And if we’re very clued up we might include testosterone, which most people think is a guy thing but women produce a small amount in the adrenals and ovaries.

Each one of these hormones is an influential contributor to the signs of perimenopause and beyond such as sleep disturbance, changes in body temperature and mood swings BUT they’re not the only players.

And then were 6 (hormones)

The menopausal years from perimenopause through to post-menopause involve a cascade of hormones and they’re all interconnected. The aforementioned estrogen, progesterone and testosterone (sex hormones) work together with cortisol (the stress hormone), insulin (the fat storage hormone) and the thyroid (the metabolism hormone).

1. EstrogenIt’s our main female sex hormone and regulates our reproductive system telling it when to produce an egg during menstruation and instructing our body to give us a womanly shape. Though the adrenals and body fat do produce estrogen our main production house is in the ovaries. However, as we go into perimenopause our ovarian estrogen levels decrease dramatically and – all too often – erratically which can affect hormonal balance. At around 50 the ovaries stop producing estrogen and the adrenal glands and body fat take over but in greatly diminished quantities. And as estrogen gives us our ‘juice’ and keeps our skin plump, our vagina moist and elastic, and our joints supple we can begin to notice changes.

2. ProgesteroneOh I love progesterone! It’s often called nature’s antidepressant and keeps us nice and relaxed, promotes sleep and helps with bone and muscle health. It’s also responsible for things like maintaining pregnancy and is essential to our fertile years. Our progesterone levels begin diminishing around 35 when our egg reserve starts to fall – this is one reason for menstrual changes – and it happens long before our ovarian estrogen declines. Falling progesterone is believed to be a main contributor to the sometimes unpleasant, often inconvenient, effects we may experience as we hit perimenopause. While progesterone levels have lessened, our estrogen may be fluctuating wildly sending hormonal balance into disarray so as well as diminished estrogen there can be times when we experience high estrogen or estrogen dominance. (I’ll write a more in-depth piece on estrogen dominance soon.)

3. TestosteroneWe produce small amounts of the male androgen hormone in our ovaries and adrenals reaching peak levels in our 20s. Testosterone instructs our body to produce pubic hair, helps with reproduction and is related to our sex drive. As with estrogen and progesterone, our testosterone levels begin to decline as we grow older and have halved by the time we’re in our 40s. Though related more to ageing than menopause it’s thought to be behind a lower sex drive and ‘lady whiskers‘.

4. CortisolCortisol is known as the stress hormone because it’s released by the adrenals – small glands that sit on top of our kidneys – when our brain perceives we’re in danger. The problems begin because the brain doesn’t understand that being stuck in traffic or fighting with our hubby isn’t life threatening and it hunkers down and acts as if a tiger is chasing us when we’re uptight. As a result many of us are in a constant stage of high cortisol. Quite apart from it not being an ideal state to be in, high cortisol can lead to carbohydrate and sugar cravings, belly fat, impacts our thyroid (metabolism) and affects the production of progesterone.

5. ThyroidThe thyroid is in charge of our metabolism. A healthy thyroid is crucial in many ways but it can often get out of kilter during the meno years. If we get elevated cortisol (as above) it puts our body into survival mode and encourages our thyroid to turn down our metabolism to save energy for the future. Progesterone helps support our thyroid so our diminished progesterone can also affect the thyroid’s efficacy leading to fatigue, weight gain, cold hands and feet, hair loss and depression.

6. InsulinInsulin is produced in the pancreas – a small bean shaped gland – and its job is to keep our blood sugar stable and store any excess fuel as fat. If we’re eating a highly refined diet, lots of sugar or are stressed (cortisol produces blood sugar), the pancreas pumps insulin out to help stabilise and reduce the blood sugar surges these things can cause. Over time, often in midlife, this leads to insulin resistance, which is rampant in the world today and contributes to obesity and pre-diabetes. It occurs because if it’s served up a continual diet of refined foods the pancreas becomes weaker and can’t put out enough insulin. Sugar then pools in the blood draining energy, inhibiting mood, bringing on brain fog and being a major contributor to weight gain.

Every. Body. Is. Different.

It’s a complicated hormonal dance and something we can only touch on here and give you broad guidelines and descriptions. As you know we’re all different. Some people are more sensitive to some aspects of physiology than others. This is why it can be useful to look at your genetics and see how your mother and grandmother fared during their meno years.
